Jon Jones Says He 'Absolutely Sucked' At Football, Unlike NFL Brothers

Jon Jones' family is filled with Super Bowl champs, but the UFC superstar tells TMZ Sports he had zero chance of having a career on the football field -- 'cause he said he "absolutely sucked" at the sport.

Of course, Jones' older brother, Arthur, played 8 seasons as a defensive tackle for the Ravens, Colts, and Commanders ... and his younger bro, Chandler, currently plays defensive end for the Raiders.

With that being said, football is clearly in the Jones DNA ... so when we asked Jon if he could have followed in their footsteps, Bones made no bones about it -- he was ass.

"I absolutely sucked on the football field," Jones told us. "I was no good at all. I didn't play until my senior year [of high school]. I was always on the team, but I never got to play.

Jones -- who holds a 26-1 record in the UFC -- says he just didn't get the Xs and Os, coverages, or play calling behind the game ... and playing Madden didn't help either.

"I sucked at football. I made a hell of a benchwarmer, though," Jones said.

But, don't feel bad for the guy -- Jones ended up becoming one of the greatest mixed martial artists ever ... and he's back in the Octagon on March 4 to face 11-1 Ciryl Gane -- his first fight in over 3 years.

"A lot of people wanted to take a warm-up fight," Jones said. "I'm going right at one of the best talents the UFC has ever seen."
